PASSAGE 2: Read this passage to answer questions 13-17. Sunscreen [A] From broad-brimmed hats to UV-blocking sunglasses, people are always looking for ways to protect themselves from too much sun. A little bit of sun exposure is necessary for our health, but too much can lead to deadly cancer. So how much is too much? A new product on the market, L’Oreal’s UV Sense, has been designed to help answer this question. [B] L’Oreal’s UV Sense is a skin sensor that detects UV rays. It is considered preventative “skintech” – a device worn on the skin to help prevent health risks, such as skin cancer. It does not block the sun physically, like sunscreen does, but it helps its wearer know how much UV light he or she is exposed to. [C] The sensor is housed in a small sticker that can fit on a person’s thumbnail. Style-conscious wearers can choose from over 50 sticker designs. They place the sticker on a pair of favorite sunglasses, a watch, or anywhere else that will receive direct sunlight. As the wearer walks to the mail box, lies out on the beach, or sits in rush-hour traffic, the device collects data on how much sun the wearer is being exposed to. The device delivers this data to the wearer’s smartphone, and alerts him or her when the level of UV rays is dangerously high. This information prompts the wearer to seek shade or apply more sunscreen. [D] This product differs from other wearable devices in that it is meant to be used for a short period of time until wearers learn which situations cause them to get the most UV rays. Wearers use the sticker for about two weeks and then disposes of it. The expectation is that wearers will become more aware of their sun exposure and change their habits or lifestyle accordingly. This means consumers can benefit from an inexpensive product, since longer-lasting ones cost hundreds to thousands of dollars. [E] So why would a cosmetic company like L’Oreal invest in technology that consumers will only use once or twice? The cosmetic giant understands that wearable devices are the latest trend on the market. They also understand how concerned consumers are about the rise of skin cancer. In response to their market research, L’Oreal wants to take the lead before other skincare companies develop similar products. The quest for developing preventative skintech has just begun and will most likely never end. QUESTION:  What does cosmetic giant in paragraph E refer to?

“If you want something done, give it to a busy person.” That advice sounds strange at first, but people with energy and ambition often get results. Time and again, people with ambition accomplish things that others thought were impossible. Whether a person wants to set a world record, or rise to the top of a company, ambition is one of the qualities that is most needed. Which of these choices best sums up what the paragraph is about in one sentence?
